TEANECK — New sidewalks, wheelchair-accessible crosswalks and curb ramps and pedestrian countdown signals are among the pedestrian-friendly improvements being made to a heavily traveled stretch of Route 4 in Teaneck, according to the state Department of Transportation.

New Prince Concrete Construction Inc., this week is installing signs and doing other work that requires periodic closings of the road shoulder during the day, officials said.

The improvements will be made to the River Road interchange, near Fairleigh Dickinson University; the Teaneck Road interchange; the corner of Sussex Road and Billington Road; and the area of Faragut Drive, Webster Avenue, Alfred Avenue and Decatur Avenue, according to the DOT.

Concrete barriers will be used for traffic control, but the DOT doesn’t anticipate major delays for motorists.

The project will cost $846,000 and is expected to be completed by the end of spring.

It fits in with the DOT’s “Complete Streets” policy of building roads with cyclists, pedestrians and motorists in mind.
